te pump I assure 111 t@ th@ l afinar@ mh contained in them is displaced by water. This being done the barren residues may' be removed as follower-The vacuum on the conduits 3 and 4 is disconnected and instead water or `air under pressure isfadmitted.

The result'of this-is to form a low pressure in .the .air spaces of the filter devices, which causes the cakes to fall from the filter devices into the lowerportion of the main chamber. It will be observed that as every other frame -is Aconnected with the conduit 3,. and the alternate'ones are connected with 4, this arrangement allows the `celtes from onehalf of the filter devices to be detached at e time so as not toovercrowd the space with residues- Assuming that thevaciium has been continued on 3 and cakes will have fetached t einselves' the filter devices connected with 4 and have -fallen into the bottom of vthe chamberA 18.

Compressed air is now admitted through the l pipe 34 and the valve 35 andvalvel oiA ther pipe 15, is opened, with the result 'that the residues in the bottom of chamber1-18 arel forced through the ports/17I intothe lconduit 7 and out through the ipe l5` teenyconvenient point. l Having t ius cleared the.

chamber of its residue the cakes attached, tor the filter devices connected with tbecondui't i are removed in the same manner. At this' stage it is advisable to admit water under pressure, through the conduit 2, b' meansot the pipe 21 and the valve i9, w ich forces and the Washing of the seine, but the device "ist 'may be used with ,equally satisfactory re suitsin the iltration oi'juice iii a sugar fac to or in the filtration of any liquid.
